What Are Common Thermostat Problems That Cause It Not To Work?

Common thermostat failures come from incorrect mode or temperature settings, a tripped breaker that cuts power, miscalibration, or loose control wiring. Our technicians calibrate thermostats, tighten electrical connections, and test safety controls during service. If the thermostat checks out, we troubleshoot the HVAC system for the root cause. 24/7 help is available in the Bloomington–Normal area.

Quick checks:

• Confirm settings are on Heat or Cool, not just circulate.
• Check your breaker box for a tripped switch.
• If problems persist, book diagnostic service.
